How to use #df2e43

Derived from its contrast, chroma and lightness — not from taste.

Works well for
  • Body text and links on white
  • Text and icons on dark surfaces
  • Primary buttons and calls to action
  • Focus rings, active and selected states
  • Brand accents, badges and data highlights
  • Chart series and data categories
Use with care
  • Full-page backgrounds — tiring over long sessions
  • Status meaning — pair it with an icon or label, never colour alone
  • Pairing with a same-lightness hue — edges vibrate

Meaning and mood

What a colour in this family tends to signal, and how this particular chroma and lightness change the reading.

urgentappetisingboldphysical

Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing.

This is a confident chroma: strong enough to lead a brand, restrained enough to live in an interface all day. The mid lightness keeps it versatile in both themes.

Worth knowing

It is also the universal error colour. Use it as a brand accent and users may read a warning that is not there.

Bottom row of hexes is the flattened result over white — use those when a design tool refuses transparency, or when you need a solid fallback.

#df2e43, answered

What color is #df2e43?

#df2e43 is a balanced vivid red, closest to Crimson (ΔE2000 2.7). It sits at 353° on the hue wheel with 73% saturation and 53% lightness, which reads as warm.

What is the RGB value of #df2e43?

rgb(223, 46, 67) — 223 red, 46 green and 67 blue out of 255, or 87.5% / 18% / 26.3% by channel.

What is #df2e43 in HSL and HSV?

hsl(353, 73%, 53%) and hsv(353, 79%, 87%). HSL is what CSS takes; HSV is what your design tool's picker shows, which is why the saturation numbers rarely match.

Is #df2e43 a light or a dark color?

It is a mid-tone. Relative luminance is 0.1805 and perceived brightness is 51%, so black text on it reaches 4.61:1.

Should I use black or white text on #df2e43?

Black. It scores 4.61:1 against #df2e43, versus 4.56:1 for white — AA at any size.

Is #df2e43 accessible on a white background?

#df2e43 on white scores 4.56:1, which clears AA at every size but not AAA.

What is the complementary color of #df2e43?

#2EDFCA sits directly opposite on the wheel. Softer options are the split-complements #2EDF71 and #2E9BDF, which give the same contrast with far less vibration.

What colors go well with #df2e43?

For interface work: #FAF4F5 as the surface, #EDC0C5 for borders, #9B4B54 for secondary text, #17B57B as an accent and #6F111C for hover and pressed states. For a palette, the analogous pair #DF2E9B and #DF712E stays calm, while #2EDFCA is the loudest partner.

What is #df2e43 in CMYK for printing?

cmyk(0%, 79%, 70%, 13%). This is a screen-to-ink approximation — ask your printer for a proof before committing to a run.

Is #df2e43 warm or cool?

Warm — it scores 21 on a scale where 0 is the warmest orange and 100 the coolest azure. Nudged warmer it becomes #DF512E; nudged cooler, #E12B84.

Which Tailwind color is closest to #df2e43?

The red family — its 500 step is #ef4444, ΔE2000 6.4 away. That is a visible difference, so define #df2e43 as a custom token rather than reaching for the built-in.

How do I use #df2e43 in Tailwind CSS?

Inline it as an arbitrary value with bg-[#df2e43] or text-[#df2e43], or register the whole ramp under theme.extend.colors.brand so you get bg-brand-500 and friends. The generated 50–950 scale on this page is ready to paste into your config.

What is #df2e43 with 50% opacity?

rgba(223, 46, 67, 0.5), or #df2e4380 in eight-digit hex. Over white that composites to #EF97A1; over black, #701722.

Is #df2e43 a web-safe color?

No. The nearest web-safe colour is #CC3333, ΔE2000 5.3 away. The palette only matters for legacy displays and some email clients now.

What does the color #df2e43 mean?

As a red, it reads urgent, appetising, bold. Red arrives before the rest of the page does. It raises attention and appetite, which is why it runs food, sport and clearance pricing. At this chroma the effect is amplified — it will dominate whatever sits beside it.

What gradient works with #df2e43?
